I like this one better - again, you’re very good at setting atmosphere. It’s eerie and intriguing, kinda like a cave with a lake in it.
But who is in the lake? Or on the lake? See, if this were a game, you wouldn’t have to tell us with the theme. But if a hero is crossing the lake with an angry monster rushing to get him, there would be an ominous bass line for the monster and some kind of theme for the hero that would get mixed in here.
But maybe you don’t want it like that. Maybe you had something very different in mind. Maybe this just for an informational thing on stalactites, in which case it would be just fine.
